AP_Notify: add class to turn LED off

Browse Source 
On early versions of minlure an RGB LED was wrongly placed next to the
barometer, causing trouble on it.

Additionally depending on the LED intensity it may be a pain to leave it
turned on for boards supposed to be used for bench testing. This allows
to disable the LED by software so we don't have to remove it.
